Fix SSL Auto-Renewal Failure

The Problem

Your SSL certificate was supposed to renew automatically, and it didn't — either it's already expired and causing warnings, or you caught it close to expiry and want the underlying automation actually fixed, not just the certificate manually renewed again.

About this problem

Automatic SSL renewal (most commonly via Let's Encrypt's certbot or a hosting panel's built-in scheduler) relies on a chain of things all continuing to work silently in the background: a cron job or scheduled task actually running, the domain validation method still succeeding, file permissions remaining correct, and the renewal script itself not erroring out. Any single link breaking — a server migration that didn't carry over the cron job, a firewall change blocking the validation request, a permissions issue after a backup restore — causes silent renewal failure that nobody notices until the certificate actually expires.

Just renewing the certificate again without finding why the automation broke means you're likely to be back here in another 90 days.

What's Included

• Immediately renewing the certificate if it's expired or close to it
• Investigating exactly why the automated renewal stopped working
• Fixing the underlying cause (cron job, permissions, validation method, server configuration)
• Testing that renewal will actually succeed going forward, not just assuming it's fixed

What's NOT Included

• Switching to a different certificate authority unless that's actually the cause
• Ongoing monitoring beyond confirming the fix (see server monitoring/alerts service)
• Server-wide cron/scheduling issues unrelated to SSL renewal specifically

How It Works

1. Check the certificate's current status and renew immediately if it's expired or about to, to stop visitor-facing warnings.
2. Check whether the renewal cron job or scheduled task is actually present and running.
3. Check the domain validation method (HTTP file-based or DNS-based) is still succeeding, since a server or DNS change can silently break this.
4. Check file/directory permissions the renewal process needs, especially after a migration, backup restore, or server update.
5. Run a manual dry-run renewal to confirm the whole chain genuinely works before considering it fixed.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

Why did my SSL certificate stop auto-renewing?

Common causes include a broken or missing cron job, a changed server configuration that breaks domain validation, or file permission issues after a migration or restore.

Is it enough to just manually renew the certificate without fixing the automation?

It fixes the immediate problem but not the underlying cause, so you'll likely be back in the same situation at the next renewal cycle — fixing the automation itself is the real fix.

How do I test if SSL auto-renewal will work next time?

Most renewal tools (like certbot) support a dry-run mode that simulates the renewal process without actually requesting a new certificate, which confirms whether it would succeed.

Can a server migration break SSL auto-renewal?

Yes, very commonly — cron jobs, file paths, and validation configurations don't always carry over automatically during a migration.

Will I be notified before my SSL certificate expires?

Depends on your setup — some services send expiry warning emails, but this isn't universal, which is why fixing the actual renewal automation matters more than relying on a warning email.

Can a firewall change cause SSL renewal to fail?

Yes, if it blocks the validation request (commonly on port 80 for HTTP-based validation), the renewal will fail even though everything else looks correctly configured.
